Abstract
A time measurement circuit includes N time stamping units that each includes a dual sinusoid interpolator for achieving high timing resolution. The time measurement circuit is capable of time stamping input signals at a high re-trigger rate, and is thus well suited for quickly measuring the timing jitter of test signals in automatic test systems.
